Down here, it's called "bot trading".
Will see as little as single shares traded in a company, slowly pushing the price in a given direction, then a parcel will be bought or sold when the margin has been reached.
They aren't paying brokerage, as nobody would consistently sell $5 worth of shares with $20-$30 worth of brokerage.
Black Friday, the bots got confused, and were putting $40 shares out at 2.5c.
ASX doesn't give a rat's as they make margin on transactions.
